Electrode manufacturing apparatus including electrode alignment unit and electrode assembly manufacturing apparatus

Abstract

Electrode and electrode assembly manufacturing apparatuses include an electrode transfer unit for transferring an electrode with coating layer on surface of the electrode, a cutter for cutting the electrode transferred by the electrode transfer unit to form a unit electrode, a separator transfer unit disposed at one surface of the electrode transfer unit and configured to transfer a separator, a sensor unit for sensing the position of the unit electrode and an alignment unit for adjusting transfer speeds of outer peripheries of the unit electrode parallel to a unit electrode transfer direction to adjust the interval between unit electrodes seated on a separator surface. Whether positive and negative electrodes are aligned before stacking and laminating electrodes having different polarities is determined. The positive and negative electrodes are then stacked, whereby the occurrence of a defective electrode due to misalignment between the positive and negative electrodes is preventable.
